IHD3ER331L Equivalent & Substitute Parts

Part Overview

The IHD3ER331L is a 330 µH unshielded drum core wirewound inductor manufactured by Vishay Dale, rated for 1.6 A with a maximum DC resistance of 257 mOhm. This through-hole axial component is designed for applications requiring fixed inductance in the 330 µH range with moderate current handling capability. Substitute parts become necessary when the primary manufacturer part is unavailable, when inventory constraints require alternative sourcing, or when application requirements align with alternative component specifications within acceptable electrical and mechanical tolerances.

Key Parameters

Substitute Part Grouping Explanation

The 5900-331-RC from Bourns Inc. qualifies as a substitute based on the following alignment of critical parameters:

• Inductance Match: Both parts specify 330 µH, meeting the primary functional requirement
• Core Configuration: Both utilize unshielded drum core wirewound construction, ensuring mechanical and electromagnetic compatibility
• Mounting & Package: Both are through-hole axial components, allowing direct physical substitution in PCB layouts
• Operating Temperature Range: The 5900-331-RC operates across -55°C to 105°C, covering standard industrial and commercial temperature requirements
• Compliance Status: The 5900-331-RC is RoHS3 compliant and REACH unaffected, meeting modern regulatory requirements

Electrical Considerations: The 5900-331-RC carries a 1.2 A current rating versus the IHD3ER331L's 1.6 A rating, and a 285 mOhm maximum DCR versus 257 mOhm. These differences require application-level verification to ensure the substitute meets circuit performance requirements.

Parameter Comparison

Engineering Selection Recommendations

The 5900-331-RC is suitable as a substitute when the application circuit can operate within the lower current rating of 1.2 A and can tolerate the increased DC resistance of 285 mOhm compared to the original 257 mOhm specification. The Bourns component's documented RoHS3 compliance and REACH unaffected status provide regulatory assurance for modern manufacturing environments. Selection should be based on circuit current requirements and acceptable power dissipation margins at the specified operating point.

Frequently Asked Questions (FAQ)

Q: Can the 5900-331-RC directly replace the IHD3ER331L in all applications?

A: Direct physical substitution is possible due to matching inductance, core type, and axial through-hole packaging. However, electrical compatibility depends on whether the circuit operates at or below 1.2 A and can accommodate the 28 mOhm increase in DC resistance.

Q: What is the significance of the current rating difference?

A: The IHD3ER331L is rated for 1.6 A while the 5900-331-RC is rated for 1.2 A. If the application circuit draws current exceeding 1.2 A, the substitute part may experience thermal stress or saturation effects. Verify actual circuit current requirements before substitution.

Q: How does the increased DC resistance affect circuit performance?

A: The 5900-331-RC has a maximum DCR of 285 mOhm versus 257 mOhm for the original part. This 28 mOhm difference increases resistive losses and power dissipation. For applications sensitive to inductor losses, calculate the impact on circuit efficiency and thermal performance.

Q: Are both parts suitable for RoHS and REACH-regulated applications?

A: The 5900-331-RC is explicitly RoHS3 compliant and REACH unaffected. The IHD3ER331L compliance status is not specified in the provided data. For regulated applications, the Bourns component provides documented compliance assurance.

Q: What are the physical dimensions of each part?

A: The 5900-331-RC is specified as 0.453" diameter × 0.900" length (11.51 mm × 22.86 mm). Physical dimensions for the IHD3ER331L are not provided in the available data. Verify PCB layout clearances if space constraints exist.
